King Henry I
Natural Children of
King Henry I of England

    Kings Henry I and Charles II were the only Kings of England to beget really large broods of illegitimate offspring.  Charles, credited with 8 sons and 6 daughters, is clearly outdone by Henry with a known illegitimate offspring list consisting of 9 sons and between 12 and 15 daughters.  There may be more, too.  The name of the mother is known with varying degrees of certainly for 12 of the children. 
Perhaps King Henry had so many girlfriends and children that he forgot who belonged to whom.
